BUTTON.

Specification of Letters Patent.

Patented Nov. 4., 1919.

Application filed June 5, 1917. Serial No. 173,048.

T 0 all whom it may concern:

Be it known that I, PATRICK JoHN WVHELAN, a subject of the King of Great Britain, and a resident of Douglas in the Province of Ontario and the Dominion of Canada, have invented certain new and useful Improvements in Buttons, of which the following is a full description.

This invention relates to improvements in buttons to be used on police, naval, or like uniforms, or as society buttons, badges, collar, cuff and suit buttons of all types, and the objects of the invention are to facilitate assembling the button and to permit of its being readily attached to a garment, to cheapen the cost of production and generally to adapt the several parts to better perform the functions required of them.

WVith these and other objects in view, the invention consists essentially of the improved construction particularly described and set forth in the following specification and accompanying drawings forming part of the same.

\ In the drawings,

Figure 1 is a perspective view of the improved button.

Fig. 2 is a vertical section of the same.

Fig. 3 is a vertical section of the outer member of the improved button.

Fig. 4: is a side elevation of the outer member of the improved button, part being broken away in section.

Fig. 5 is a perspective view of the outer and inner members of the improved button as seen when about to become engaged.

Fig. 6 is a side elevation of the inner member of the button.

Fig. 7 is a plan of the inner member.

Fig. 8 is a front elevation of the tubular stem of the outer member as seen when developed into rectangular shape.

Like characters of reference refer to like parts in the several figures.

, Referring to the drawings, A represents the improved button comprising the inner member 10 and the outer member 11. The inner member 10 is provided with an elastic stem 12 having a flattened end 13, and this stem is inclosed in a sleeve 14 which terminates just short of the flattened end 13 and is provided on diametrically opposite sides with projections 15, the object of which will be made clear hereafter.

By reference to Fig. 7, it will be seen that the flattened end 13 of the spring and the projections 15 are angularly disposed'relatively to each other. The outer member 11 is provided with a stem 16 provided with a pair of recesses 18 arranged on diametrically opposite sides thereof.

One of the walls of each of the recesses 18 is formed curvili-nearly as shown at 19 and the said wall is provided adjacent to its lower end with offset recesses 20.

When engaging the inner member 10 with the outer member 11, the flattened spring portion 13 of the stem 12 and the projections 15 engages with the outer enlarged ends of the recesses 18, and as the members 10 and 11 are pressed into contact with each other, the member 10 will be rotated to a slight degree owing to the tendency of the spring 13 being twisted into alinement with the projections 15 thereby conforming to the path of travel provided by the recesses 18.

When the members 10 and 11 are closed, the resiliency of the flattened portion 13 of the stem 12 will rotate the inner member 10, so that the projections 15 engage with the recesses 20 and in this position the button is operatively assembled.

In disassembling the button, the members 10 and 11 are rotated to a slight extent in opposite directions until the flattened spring portion 13 of the stem 12 comes into alinement with the projections 15, and in this position the projections 15 will have cleared the recesses 20 and be located in the recesses 18 and a slight longitudinal pull is now applied to the members 10 and 11 withdrawing the same from engagement.

From the above description it will be seen that I have invented a button which can be quickly assembled and disassembled and can be advantageously utilized for a service button and perform the necessary functions required of it.

As many changes could be made in the above description and many apparently widely different embodiments of my invention within the scope of the claim constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limited sense.

What I claim as my invention is:

A button comprising an inner and an outer member, a sleeve on the inner memher, a spring stem in the sleeve terminating in a flattened outer end extending beyond the sleeve, projections on the sleeve, the

tubular stem on the outer member formed With arcuate recesses on the inner wall provided with offset recesses in the lower end,

the said arcuate recesses being designed to engage the projections and flattened end on the stem when the two members of the but- 10 ton are rotated to a limited extent to permit of their being engaged or disengaged.

In witness whereof I have hereunto set my hand.

PATRICK JOHN WHELAN.
